nRF24L01+ 2.4GHz radio tranceiver chip - driver ready

Erlend

I have over the last few weeks enjoyed the challenge of making an SPI driver that I am happy with, and then a driver for the fabolus and cheap nRF24L01+ radio chip.
It is incredible how gratifying it can be to see 'Hello wireless world!' pop up on the screen, after being transmitted from one prop&nRF to another prop&nRF.
It has been a bit of a bumpy ride; one example is that some of the register bits wants to have a '1' written to it - when you want to reset it to '0'. Crazy.

Nice work on both your new objects!

Erlend

Thanks!

Make that three! new objects.

Erland, thanks for a great object. I'm glad Propeller users are paying attention to the nrf24L01 modules. Arduino users have a large library of code for it. There hasn't been much for Propeller users.
I especially like that you wrote a method for frequency hopping. That should be very useful.

Erland, I modified your DEMO (Erlands PTX) to increment a value without requiring keyboard input. (I also changed it to transmit and receive on channel 7 instead of channel 113.)
In the "Transmitter" method "Bit_Count" increments but none of the 'IF" statements returned.
I modified the DEMO a second time for (ErlandsPRX) but it does not appear to respond to the PTX. What am I missing?

Erlend

If you want to transmit 1 byte, change nrf.SetPayloadWidth(0, 32) otherwise it will expect 31 more bytes.

Erlend,
Thanks your development and sharing your work on the nRF24L01+ radio chip.
I look forward to experimenting with the system.

Erland, I just noticed that I didn't change the pin numbers for my breadboards. Oops! It's working. Great object and well written. Thanks.
